Rumours have been swirling of a relationship between tennis golden girl Emma Raducanu and former Harrow head boy Carlo Agostinelli. Now, the couple have given one of the surest signs yet that love is in the air – after stepping out last Friday to celebrate Agostinelli’s 23rd birthday. Their venue of choice? Oswald’s, the glamorous private members’ club in Mayfair, frequented by A-Listers and royals (Princess Beatrice and Edoardo Mapelli Mozzi were there the same night).

Emma and Carlo arrived in style at around 7.30pm. Raducanu dazzled in a green-toned silver dress with delicate pleated skirt which swirled around her as she walked into the club. She topped the stylish outfit with a navy blazer, accessorising with low black heels which each had a black bow, and a ring on her middle finger.

Carlo, meanwhile, sported a navy blue suit, along with a co-ordinated navy shirt and white handkerchief in his top pocket. He paired the outfit with a couple of stylish navy blue velvet slippers, complete with green palm tree embroidery detail on the front. The couple reportedly left the club at around 11.30pm.

Agostinelli is the son of London-based private equity billionaire Robert Agostinelli, 70, a former Goldman Sachs banker who once tried to buy Liverpool football club. After leaving Harrow, the 23-year-old went on to attend Stanford University in the US, reading International Relations and playing soccer in his spare time. He and Raducanu were first spotted together when they shared photos from Mexico on Instagram. At the time, Agostinelli was compared to a young Rafael Nadal with his long, dark hair.

In mid-June, Emma Raducanu was photographed outside Agostinelli’s £2 million pound mansion block in Kensington, and the rumours seemed to be truer than ever. The two were also pictured coming out of Whole Foods together at the beginning of July, looking cool and casual in relaxed outfits. Though neither Raducanu nor Agostinelli have publicly admitted to their relationship, evidence would point to the fact that the two are getting closer by the day.

Surely, there will be many more date nights to come.
